Ruby evaluation.

Ruby evaluation.

[A Soare]

I am interested whether there is a possibility to run an evaluator
of Ruby in emacs.

I find nothing useful on wiki, etc.

I have vanilla emacs-23.1 and M-x run-ruby [No match]
so I suspect you installed something ruby related.  The OP needs that info.

I have the following in my ~/.emacs (note the run-ruby):

;; ruby mode
(autoload 'ruby-mode "ruby-mode" "Load ruby-mode")
(add-hook 'ruby-mode-hook 'turn-on-font-lock)

;; associate ruby-mode with .rb files and .rjs files
(add-to-list 'auto-mode-alist '(".rb$" . ruby-mode))
(add-to-list 'auto-mode-alist '(".rjs$" . ruby-mode))
(add-to-list 'auto-mode-alist '(".rake$" . ruby-mode))

(setq interpreter-mode-alist (append '(("ruby" . ruby-mode))
                                       interpreter-mode-alist))

;; Ruby-Interpreter:
(autoload 'run-ruby "inf-ruby"
    "Run an inferior Ruby process")
(autoload 'inf-ruby-keys "inf-ruby"
    "Set local key defs for inf-ruby in ruby-mode")
(add-hook 'ruby-mode-hook
            '(lambda ()
               (inf-ruby-keys)
               ))

I guess it should be noted that inf-ruby.el is not part of the emacs
distribution. It comes with ruby i think.

Perfect.

I had actually done load-lib ruby-mode before trying M-x run ruby.
I think this is exactly what the OP (and followers) will need.

The command is M-x run-ruby RET
See:
http://lisp.tistory.com/entry/Rubymode-in-Emacs



Also, to be able to C-x C-e ruby expressions from any .rb files, you can use:
http://www.informatimago.com/develop/emacs/emacs/pjb-ruby.el


with:
(setf inferior-ruby-first-prompt-pattern "^\\(irb\\(.*\\)[>*\"'] *\\|(rdb:[0-9]*) \\)") 
(setf inferior-ruby-prompt-pattern       "^\\(irb(.*)[0-9:]+[>*\"'] *\\|(rdb:[0-9]*) *\\)+")
